To all whom 'it-may mwerni Be it known that I, ALiiiiii'rL. AUsriia, a

citizen of the United States, and a resident of Lakewood, county of Cuyahoga, andv State of Ohio, have invented a new and .use-

ful Iml'oveme'ntin Steam-Generators, of.`

which t e following is a specicatiomthe principle of the invention bein herein explained and the best inode inw cli' I have 'contemplated applying that principle, so as to distinguish it from other inventions.

,The present invention relates to steam.

generators, and its general object is the provision of a generator characterized by economy of space occupied and b maximumefficiency in the generation' o steam with a minimum amount of fuel consumption. 'y To the accomplishment of these and related ends said invention, then, consists of the in ns hereinafter fully described and particu arly pointed outin the claims.

The annexed drawin `and the following description set forth in etail certain mechanism embodyingv my invention, such disclosed means constituting, however, Ibut one of the various -medianical forms in which the princi leof the invention ma be used.

In sai annexed drawing :-t e figure is a vertical sectionof the generator.

The generator comprises a casin 1 formed of suitable material above which is disposed a. water chamber 2, and the casing 1 and chamber 2 maybe formed separately or may be formed by placing a partition within an integral casi as desired. The water chamber 2 is provided with a sightglass 3 and with an inlet 4 connected with any desired source of su ply. Pipes 5, of which there may be any esired number, depend from the bottoni 'of the" water chamber 2 into the cas#V in 1 and arel preferably formed in helical coils 6. I have also found it advantageous to bend certain portions of the pipe between the ends of the coilvertically as at 7, and then rebend them back into 'a coil. At the lower ends ofthe coils, as at 8, the Iii es are (bent u wardly and extend para ey with each o er substantially through the center of the casing 1 and the water chamber 2 to a point at or near lthe top of the chamber. The pipes 5 preferabl terminate' near the top of the casing 1, and t eir continuation is formed jlpiiied to the ends of by pipes 13, which are pipes 5 by joints 16. T e upwardl extending portions of the pipes within e cas' 1, are inclosed by an asbestos tube 9.

as especi tube is supported in the water chamber,

and'at its upper end is rov dedwith' a perforated cap 17, in w ich perforation is threaded a second tube 18', paced from the pipel 10. A cap 19 is secui ed tothe 'lower end of tube 18, and it is thm ugh the tube 18 that the pipes 5 extend, or tl pir continuation 13, if thepipes be jointed c nes.' Above the upper ends of the pipes is a connection 11 for ,conductinthe' 4generated steam to its place of 'gas pi vis disposed immediately below the tu 9 :ind is connected withI any suitable source.

In'the use of my im rovf d enerator, the water chamber is pa y leg and the water descends thri ughrthepipes 5 by gravity. A blast from the gas pipe is directed into the tube 9, an 1l this blast also draws in air through the o1 ening below the side of the casingl. AsV 'the cold water with Vwater,

it is struck by theintense f rc'ed'blast from the gas ipe, -and isinstai t1 iashedinto steam. raet-ically all of t e -hot gasl is driven through the tube 9 so thatin the upwardly extending rtio is o f the pi es,

the steam is dried an expal ided. It w' `be noted t-hatt-here is an air s] `ace betweentlie two concentric tubes which lnclose the'pipes within thewater chamber, ind some of the hot ases rise into this air space and serve to e ectually insulate the s :eam pipes from the cold water. The majority of the hot gases after rising through he tube 9, strike -the bottom of the water cha nber and are re- Iiected downwardly, and fumes pass ofi' through a pipe 20. It will tli erefore beunderstood that the present inve ition 4rovides a nerator of the Hash t5 pe, w ich is fed y gravity, and bymeans of whichycold Water ma 'V credibly s ort time, and w th an extremely small fuely consumption. ,Thel im rtant oint of construction in a1 is end is thatthe pipes are subje( ted to heat only at the point at which- 0 the that is within the space inci sed by be flashed into steam inan 1n,

start u wardly e lower" tube. Th portions ofthe pipes outside4 off this lower t be 9 are subjec ed to ractically p none of the heat and as all if the; eat is di-` rected' a inst the pipes at the one pointat which t ey'ae bent upwi rdly ashing is bound -to occur. Y

'Althoulli I have describ :ad invention y ada ted for t zie generation of steam, it is equ y adapta ile to the proviregards 'the mechanism sion of hot water." When it is desired to use it as a water heater, the ipes will not extend higher than the leve of the water in the'chamber but will referably stop short of thewater level. y regulation ofthe heat directed at the lower ends of the pipes the cold water can be instantly heated as it starts into the uprisers.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as erein described provided the means stated by any of the ollowing claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctlf claim as m invention 1. n a device o the character described, the combination of a water chamber, pipes depending from said chamber and bent upwardly'at their lower ends, a tube incl`osin the upwardlyl extending portions of sai pipes, and a ot blast directed into the bottom o f saidv tube and arranged so that the descending portions of said pipesare subjected to su stantiallyno heat and so that substantially the full force of said blast is appliedto said pipes Aat the points where they are bent upwardly.-

2., In a device of the character described, the combination of a water chamber, pipes depending from said chambei` and bent up-l wardl at their ,lower ends, thel upwardly:l exten ing portions of said pipes extending through said chamber to a level above the water and 'being insulated fremd-said water, a tube inclosng the upwardly extending portions of said ipes `below said chamber,

and a hot blast directed into the lower end of said tube and being so arranged that the .depending portions of said pipes are subjected to substantially no heat and substantially the full force of said blast is applied to said pipes at the points where they are bent upwardly.

3. In adevice `of the character described, the combination of a casing; a water chamber above said casing; a pipe `depending from said chamber into said casing, said pipe being bent at its lower end and' extending thence upwardly substantially through the center of said casing and chamber; a

- tube inclosin the portion of said ipe within said cham er; a second'tube inc osing the l upwardly extending portion of said pipe within said casing; and a heater below'said second tube.

a device of the character described,

` tending thence the combination of a casin a water chamber above said casing; a p urality of pipes depending from said chamber into said casin said pipes being bent at their lower en sand extendin thence upwardly substantially through t e center of said casing and chamber; a tube inclosng the portions of said pipes within said chamber; a second tube inclosng the upwardly extending portions of said pi es within said casing and a heater below said second tube.

5. In a device of thecharacter described, the combination of a casing; a water chamber above said casing; a plurality' oipes depending in helical coils from said c amber into said casin said pipes being bent at the lower ends o said coils and extending thence u wardly substantially through the center o said casing and`chamber; a tube inclosng the portions of said pipes withinV said chamber; a second tube inclosng the upwardly extending portions of said pipes within said casing; and a heater below said second tube.

6. In a device of the character described, the combination of a casing; a water chainber above said'casing; a plurality of ipes depending in helical coils from said c 1amber into said casing and bein formed between the ends of said coils with vertically extendin rebent portions, said pipes being bent at t e lower ends of said coils and exupwardly substantially through the center of said casin and chamber; a tube inclosng the portions of said pipes withinsaid chamber; a'second tube inclosng the upwardly extending v poi-tions of said pipes within said casing; and a v' heater below said second tube.

7. In a device of the character described, the combination of a water chamber, a casing below the chamber, two. spaced` concentric tubes extending through -the chamber,
